A25 does not support ext4. Enter 'cat /proc/filesystems' in adb terminal or terminal emulator on your phone. You will get a good idea what file system is supported and what is not. And A25 is MT6575 based. File system support does not depend on the hardware platform. It only depends on whether the Linux kernel in the device supports it or not. So of course, if we made a custom kernel for A25, it can support ext2, ext4, swapping, zram. Swap and zram support will make this phone even more efficient than it already is. For instance, it will be able to run Dead Trigger without closing out of low memory (RAM) which it always does now. To prepare a custom kernel, we need the original kernel source for A25. I wonder if it is inside the package available on Micromax FTP server.
